Identification of indole-3-carboxylic acid as mediator of priming against Plectosphaerella cucumerina
Gamir, Jordi; Pastor, Victoria; Cerezo García, Miguel; Flors, Victor Elsevier (2012)Plant resistance against the necrotrophic pathogen Plectosphaerella cucumerina is mediated by a combination of several hormonal-controlled signalling pathways. The priming agent β-aminobutyric acid (BABA) is able to induce ... -
